I guess unless one is cashing out, or one is needing the money now, one shouldn't worry too much about the price fluctuation. It is natural for markets to go up and down. As long as the 'company' is sound, prices will go up again when the market is positive. At the moment, as you pointed out, it is a good time to accumulate SP, or load up / buy more Steem - if you are so inclined.
